sl0ppty: the status line says which pane, not just how many

A bare count answered "how big is this tab" and left "where am I in it" to be
worked out by counting frames — which is exactly the question you have once a
tab has collapsed into a list and only one pane is open, and exactly when
counting frames stops working. It reads `pane 2/5` now.

It also stops looking like the session count in the opposite corner. Two
numbers in two corners, both rendered "N panes" and disagreeing, was a puzzle
the reader had to solve once and then remember.

Both bars also take a `status_pad` for how far they are held off the left and
right edges. They were using `gap * gap_aspect`, which is the space around the
*panes*: the two match at the defaults and there was never a reason they had to
be the same number.

The count is kept as a fallback for when nothing is focused, which should not
happen but says something true if it does.
